MOSCOW — Amnesty International says that more than 100 leading musicians are calling for release of jailed members of the Russian punk group Pussy Riot.

Amnesty said Monday that Adele, U2, Madonna, Yoko Ono, Radiohead, Patti Smith, Bruce Springsteen, Ke$ha, Sir Paul McCartney and Sting were among those who signed an open letter organized by the group.

The musicians say in the letter that the impact of Pussy Riot's "shockingly unjust trial and imprisonment has spread far and wide, especially among your fellow artists, musicians and citizens around the world."
